We’re solving every piece of the battery puzzle
Seeo’s safe and energy-dense solid-state cell can power everything from cars to homes to aircraft.
Seeo is founded with the goal of creating a new class of high-energy rechargeable lithium-ion batteries based on a nanostructured polymer electrolyte initially developed at Lawrence Berkeley National Laboratory.
SEEO deep battery cell development experience
Seeo develops DryLyte, a lithium-stable solid-state electrolyte/separator.
Seeo - safety of solid-state battery cells
Seeo moves to Hayward and establishes a pilot line to develop large-format cells and processes.
Seeo - what makes our team great
Seeo develops a cell design and processes at pilot scale to build high-quality (Li/LFP) large-format cells.
Seeo demonstrates DryLyte stability (>2000 cycles), safety and reproducibility with large-format cells.
Seeo scales up DryLyte chemical processes to make ton quantities with high quality and cost efficiency.
Seeo - cost-effective manufacturing of solid-state battery cell
Seeo builds up multi-kWh battery modules, fully tested by USABC.
Seeo focuses on high-energy cells and development of a NCx cathode system (polymer, salt, additive, CAM) with stability up to 80°C.
Seeo develops new purification and rolling methods for lithium foil, as well as chemical treatment to reduce interface resistance.
Seeo - polymer advantages for solid-state battery cells
Seeo takes a leap forward with its next-generation polymer electrolyte, which enables cells with NCM cathodes.
Seeo builds 250Wh/kg (15 Ah) cells.
Seeo develops a next-generation solid-state electrolyte/separator that can be operated with NCM cathode active material.
Target: Development of a solid-state, high-energy (>20 Ah) battery cell with 350Wh/kg energy density.
Target: Development of a solid-state, high-energy (>30 Ah) battery cell with 450Wh/kg energy density.
